Application filed December To all whom it may concern Be it known that I,.GARRE1T RUssnLL, a

subject of the King offGreat Britain, residing at Elsternwlck, in the State of Victoria, Commonwealth of Australia, have invented new and useful Improvements in Jointing and Fastening Means, of which the following is a specification.

This invention relates to an improved jointing device for rigidly fastening members or constructional integers in such a manner as will provide for their ready disconnection when necessary, and it is particularly adapted for use in jointing the wooden members of bedsteads, tables, chairs and other articles of furniture: for fastening the sides and ends of packing cases and crates: for connecting the members of scaffolding and of moulds used in concrete construction and for other analogous purposes.

The invention although primarily devised for jointing wooden members is not limited to that use, as it can he applied with equal 'l'acility for the functioning of metal members, but more particularly in metal constructions wherein the provision of means 'iermittiug the ready assembly and disconnection of parts is the desideratum.

According to the invention, I provide a. jointing device comprising two small plates having members adapted to be interfitted and then locked by a detachable pin or key. Each of the aforesaid plates is constructed having loops in the nature of arch-shaped projections with slots between said loops, and the slots of the one plate are arranged to accommodate the loops of the opposed I plate when the two plates are placed in abutment. A locking pin or key inserted through the registerlng loops rigidlv retains the two plates n interlocked engagement.

Reference is had to the accompanying drawings, wherein a, 1924.- serial no. 753,590;

a locking pin' or 'key forthe interfitting plates of the jointing device:

Figure ing each of the plates formed with two series of loops and-locked in interfitting'engagement by two pins.

Figure 8' is a view' illustrating further form of the invention for effecting a corner joint. W Figure 9 is a view showing 'oneof the members of the jointingi'device constructed with tongues for attachment purposes in lieu of screw fastenings. .Figure 10 is a plan view illustrating an adaptation of the invention for the dual purpose of jointing and corner bracing. P

The improved jointing device in the representative form of the invention illustrated in Figures 1 to'6 '"comprisestwo plates 2 and 3 having holes'4,throughj which screws 5 are passed to afli'xsaid plates in requiredrelative positions to the members thatare to be jointed. a r

The plate-2 is constructed having three loops or arched projections 6 correspondingdimensionally and arranged in alignment,

and between said loops there-are-fOrrried' slots 7 in said plate. i

The co-operating plate 3 of the ointing device is constructed with two loops 0r arched straps 8 corresponding dimensionally and in aligned arrangement and havinga central and two'margial slots 9.

- The slots 7 and 9 have a width slightly ex ceeding that of the loops 8 ;an'd '6, respectively. The two plates are adapted tobe' brought 4 1s a perspective view of another form of the invention characterized by hav into surfaceabutment, Whenthe 'loops 6 of the plate2 register with and project through the slots 9 of 'thejplate 3, while the loops 8 of the plate3-"register with" andproject through the slots 7 of the opposed pla'te2.

A locking pin-or key 10 having its stem of oval or elliptical shape in cross-section and provided with an arm 11 at its upper end is then passed through the series of loops 6 and 8 and by being slightly'turned is caused to impinge with required pressure against the surfaces of said loops to thus maintain the two opposed platesin interlocked engagement. 'Other forms of locking pins may be used, or alternatively a key constructed to form a driving fit with the said loops (5 and 8 may be provided, but for
